resents the paper in the various phases of its evolution. modiication of the means for the general control of the mechanisms. Fig. 25 illustrates a. modiied method of controlling some or the parts. Figs. 26, 27 (a, Z), c) and 28' are details drawn io a larger scale.

The paper 1 (Figs. 1 and 2) which may he of any kind is arranged in the machine in a roll, `this roll being supported by t-wo brackets 2 fixed in ihe 'frame and furnished with screw pivots 3, 'whose ends engage the centers of the adjacent ends of the wooden roller i upon which the roll of paper is mounted.

rllie paper is ii'iiially arranged inposition by hand; it then unwinds automatically. ltis passed 1oeneath a wooden roller 5 rotating upon a shaft 25 ournaled in hearings (i which are loosely mounted upon Vertical screws 3"(li`ig. 2) and are forced Jtoward the work 'table 2G by the springs 8 encircling said screws, so 'that said roller will maintain the paper tautand. will feed it forward, illus preventing the displacement which might otherwise take place acci-dentally until the paper is engaged by the disks W hen so positioned, the paper will move forward automatically, as soon as the machine is ,sinai bcd, under the influence of the mechanism hereinafter described. A

The two disks 9 1, 2 and 11i) are loose upon *che shaft 10 which is journaled in the bearings 11 siidable vertically upon screws 12 and said disks are kept at an exact dist-ance apart from each other by means of the interposed spring 15 which encircles said shaft and acts against two washers 1-3 ymounted loosely thereupon, so as no cause said disks to frictionally engage two xed washers 3.2i. 'When theshaft/ 18, which. is mounted in the supports 190', is rotated by means of its connection' with 'the main drive shaft, the sectors 17 fixed upon said sha-it 1S` will rotate therewith .and their peripheral ribs 17 'Will engage the perisheries or' disks 9, which latter are depressed by the springs 13, (Fig. 14) so tietthe paper will be held between said .sectors and disks, as the saine rotatie, and will be fed4 or advanced a distance equal to the length ofthe arcs through which the sectors more.

During the. term that. the mechanisms for successively .forming the various packets, (as many as 1000 of which can be made. per; hour) are in operation, the measuring mech- Figs. 22, 23 and 24 represent a loo sprockets 20, 21said shaft being supported in bearings 23-24', (Figs. 4 and 5), connected toa wooden table 28 that is mounted above the general Work table 26 by means of -its legs 30. Said-legs rest upon the frame 51 which supports table 26 and is itself mounted upon table 81 of the machine, and upon table 81 is mounted the main` drive shaft, the latter being provided with a pul'- ley 75 connected withthe motor or other` device whereby said shaft is driven. The shaft 44 above referred to carries a cam 29 designed to engage a roller 31 fixed on the operating lever 32, (Figs. 4 and 5) one end of this lever is pivoted to a rod 33 slidably mounted in a support 34, while its other end is pivoted to an arm 85 fixed on a rockshaft 36 carried by the supports 39 and 40, sothat.

the actuation of said lever Will effect that of said rock shaft 36. 1

As a result of the actuation of the rock shaft,'the elliptical cover 38 whichis fixed thereupon by `means of the arm 37 and which, in the position of repose, (Fig. 5),

rao

closes the chamber 41 from below,v4 (Figs. 4' and 5, broken lines, and Fig. 6), opens dovvn Ward, (Fig. 4), allowing the powder contained in the chamber to fall; the spring 49 then rocks shaft 36 in the opposite direction, thereby again closing chamber 41. At the same time, the pinions 43, 43, fixed on4 their shafts 44, 22, impart a rotary movement to 2 the latter shaft in such a manner that the fan-shaped cover 45, (Fig. 6) connected to the sleeve 46 secured to said shaft is brought into position to close chamber 41 from above. Sleeve 46 carries the agitators 222 and 223, and loosely surrounds a second sleeve 22 'through whiclishaft 22 also loosely passes. 1n 'its fall the powder is conducted on to the paper at the proper place through the sheet metal conduit 47, (Fig. 4), and its quantity mayvbe increased Yor diminished by turning the knob 48 (Figs. 2, 6-and 20) secured on one end of a rod 48 whose other end is attached to a sliding plate 151 which'latter may thus be moved forward or backward, to regulate the size of the aperture of chamknife 50, which is so mounted as to be capable of rocking movement in the frame 51,.

, is pivoted at 52 to a support 53 extending from said frame, and is connected at 55 to one end of a vertical rod 54 whose other lever 56 which is pivoted, in turn, to a depending bracket 190. This lever is: pro' vided with a roller 59 'which is engaged by a cam 58 mounted on the rotating shaft 18, so that the depression of said lever by said cam Will effect a corresponding depression of said knife, the cutting portion 60 ofthe knife coacting with that of a blade 61 fixed to the plate 62, so as to sever the Apaper located in its path, after which the spring 63 will cause the knife to returntol its initial position. When the paper is thus cut'tofthe proper size for making a packet, the two angular fingers 64, (Figs. 1 and 10), joined to the lever 67 by the collar 70 are released Y from the pressure of the cam 65 against the roller 68 on said lever,A (Fig. 10), are depressed by the springs 66, thus holding the paper rmly in place. At this moment the :g5

two jointed arms 69, 85, (Figs. 1, 7, 8, 9, 10, 11, 12) ,carrying the small plate 84 (Figs. 1 and 12), are broughtinto operation by the actuation of the rock shaft 71 to which the arms 69 are secured, said shaft 71 being` moved through approximately two-thirds of a revolution by the sprockets 72 driven by i the chain 73,l (Figs. 7 and 12).

Chain 73 is actuated by means of a lever 74 which is` loosely connected to shaft 27 and is provided with a roller 77 that is engaged by cam 76, shaft 27 being journaled iii supports 190, as shown.

The'arms 69 and 85, which are swung to the left when shaft 71 isrocked as `above described, are brought into engagement with the piece of cut paper firmly held bythe stops 64 and fold the same upon itself as indicated by the letter a, (Fig. 21). The

small spring 77 is held by the screw '78 on the arm andserves to extend said arm and the adjacent arm 69 until stopped by the projection 89. The said jointed arms being thus retained in a given position by the profile of the cani 76, the plate 84 causes the outer edge of the folded piece of paper to=rest upon the angular parts 84 andv 98, which parts serve to fold the longer portion vof the paper once inl the manner indicated at 5, Fig. 21, and then in the manner indicated at c in the same figure; these folders` are then brought into operation. The folder 84 has a rocking movement in the supports 86, (Fig. l) of about a half-revolution, which movement is imparted to it by the sprocket 87 and the chain 80, (Figs. 10 and 11), said chain being connected with a lever 89 controlledpby cam 92,1the peripheral edge.

of which bears upon t e roller 90 carried by said lever. During its movement, said folder is turned or rocked from its normal position, (Figs. 7 and 11 in broken lines), wherein it presses against the folder 98, the ends of the paper arranged as shown at b in Fig. 21. At the saine time, the cam 76 Losses@ which has effected a portion of its revolution, (Fig. 12), reaches a position when the roller 77 of the lever 74 is enabled to enter its peripheral recess 76', whereupon the i arms 85, 69, released by the movement of the lever will be drawn `downward by the counter spring 91, (Figs. 7 and 12).

The small pla-te 84 moves away from the r "ice of the folder 84, and will come to est at the stop 94 during the time that said older is rocked by cam 92, so that when 'he said folder reaches the position where rests with its upper side against the ts (sig. 21).

now necessary to fold the' packet lat- .y. l,Vith this object the folding and npressing mechanism becomes operative, .,igs. 10 and 17). This mechanism con- .sts ot a. plate 102 iixed by means of the connection 108 to the rod 107 and provided at opposite sides with laterally-projecting wings 103 which are adopted to be folded je downwardly boolrwise but are held norn ally on a level with the plate 102 by the op 105 and by the springs 105 in such a nner es to constitute a. rectangular plate o.. the same size as the packet. The rod 107 is connected wit a movable frame formed by the rods 111A connected above by the cross niece 112 and below by two nuts screnf'eo into the sleeves 1102 (see detail,-

Qilig. 19), and guided in its vertical move- -U 1. 1 -2 ...o nient by the siecle supports 113 sliding Y`older 98, the paper will have been given` first longitudinal told, indicated at 5,; At this moment, the cam 76' continues its rotation, and again depresses: he lever 74 downward and with it the arms I move downward toward the ston 94 F i ing forward when the folder 84 ei'iects itsl return movement underthe influence of the' retain said rod 107 and the plate 102 in oblique position, (Figs. 2 and 16, broken lines). Txvl/'hen the cam 148 on shaft 18 strikes against the roller 109 fixed to a. lever 110', it carries down with it the mechanism as a'whole so that the latter when pressed downward, will, owing to its Weight, assume a vertical position. Then, when the cam 148 no longer engages the roller 109,-the counter springs 125 of the lever 110 press the entire mechanism upward', the t-appet 117 encountering the extension 118 will cause the rod 107 and the small plates 102 and 103 to resume their oblique position. During, the descent of the mechanism, the two plates 103 will encounter in their travel the packet 123 which has already been folded longitudinally and will. fold over its two sides until releesed by the two lugs 124 provided upon inovzable plates 124 held byv '148 having completed its eiiective movement at the same time, the frame 110, 1102, 111, 112, tion by the springs 125. The plates 108, in folding downward under the influence of the pressure exerted thereon by the two springcontrolled v.lugs 124, will leave the. completely folded and compressed packet at the proper place in the conduit 126.

The modied construction illustrated in Figs. 22, and relates to a method of controllingr the mechanism by means'ot' the shaft 1 8, insead of the method represented in Fig. 20. lt resides in the fact that instead or the cams 92, 76,108, etc., the shaft 18 carries lthe cams 140, 141, 143, 142, 144, 145, 140, 147 connected with the several oper tive parts oi the machine by the intermediary of rocking levers like those previously described. The difference consists in the fact that the rollers )fixed to the levers and intended for sliding` along the periphery of the said cams, are `guided in a grooveformed in one of the faces oiu the cam. Figs. 23 and 24 show by or" example a cam of the kind described above, in front elevation and in section on the line tony, respectively. As will be seen, the cam is provided with a groove fz parallel with its contourf Fig, 25 shows the operation ot two of these cams.

.- The modification illustrated in Figs. 25

will be returned to its initial pOS-` to 23 relatos to a different method of con- I trolling the jointed arms 69,-85 and thefolders 84 and 9S, replacing the chains previously described. The sprockets 7 2, 87 and 87 are operated by toothed sectors 128, 129, (see also the detail, Fig. 26) pivoted at 130 and 131, respectively. They are provided wit-harms 128, 129,connected4by rods 139 and 133 with the levers 132, 133 loosely mounted on the shaft 27 (see Fig. 25) and provided with pins 136,A 37; engaging 1n the grooves in the cams 134, 35 mounted on-the main shaft 18, as explained above.

The special method of connecting the rods 139,v 133 with the levers 132, 133, and eventually with the arms 128', 129 of the sectors 128, 129 is shown in Figs. 27a., 27b and 27C, which are, respectively, a side elevation, a front elevation and a plan view,

and Fig. 28. This method comprehends the forking of the free ends ofthe levers, and, also, of the arms of the sectors, and the provision of a rocking sleeve 138 in each fork, which permits the passage of the corresponding rod therethrough. This rod is maintained depressed in the sleeve by means of the nut 139 surmounted by a spring 1392 serving to absorb shocks arising inV the operation of the machine and is provided above the sleeve' with a projecting stop 1393.
